I wanted to trade some of the .40 S&W brass (3,000) that I had for some 9mm brass that I intend to reload and decided to do it today. I started counting in batches of 5, but after 300 rounds, I can see that this is going to take a LONG time to complete. I decided to use the weight approximation method to count 3,000 rounds. Put 300 rounds on my weighing scale and to my surprise. 3lbs. HMM! Does that mean that 1lb of .40S&W brass = 100 rounds?
I took 10 rounds and weighed them, 1.5oz. Wow that’s pretty close. so instead of counting up to 3,000 which I suspect, would have taken me a good hour or so, I packed three ziplock bags, 10lbs each for a total of 3,000 rounds. approx
10mins and I’m done. Great! Back to some wine and TV.
